include/config-win.h:
  use the ll and ull postfix codes for create longlong and ulonglong
  symbols.  This allows ULL(a) and LL(a) to be used in more complex
  macro definitions than the previous definitions.  This may work on
  other compilers but we just tested on Visual 7.1 and 8.0
  
  Also, define HAVE_STRNLEN for all windows platforms.  Our own strnlen
  offers no performance improvements over the CRT version.
